If you look at the pix on the first page, the third pic down, which shows the connection plate of the motherboard, you'll see two RCA audio ports in the upper right corner (next to the LED lights). Those are connected to the CD audio ports on the mobo. From there, it's a simple RCA cable from the CarPuter to the Amp.

You can easily do it straight using 3.5 pin. In this case, I soldered the RCA positive lines to the 3.5mm positive line, then ran the ground lines to the system's ground. I did this so I could still use the 3.5mm plug for standard desktop speakers when I'm working on it at my computer desk. Basically, it'll push audio through 3.5mm and the RCA ports at the same time. You can easily use a 3.5mm to RCA adapter for the same results.
